Methods of setting up, caring for and later removing a temporary rasta hairstyle

ABSTRACT

A method of setting up, caring for and later removing a temporary rasta hairstyle is disclosed. This method includes applying a roughness-increasing substance to the hair to roughen the hair, optionally, but preferably, applying an adherence-increasing substance to the hair to increase adherence of hairs to each other, and subsequently setting up the temporary rasta hairstyle by intertwining hair strandwise. The cleaning of the temporary rasta hairstyle occurs preferably using a concave sponge, without disturbing the temporary rasta hairstyle. To again remove the temporary rasta hairstyle a composition that increases the combability is applied to the hair and the rasta strands are opened and unwound or untwisted. Multi-component kits and compositions for performing the method are also described.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to methods for setting up, caring for and later removing a temporary rasta hairstyle, to compositions and ingredients used in the methods and to multi-part kits for performing the methods.

[0003] 2. Description of the Related Art

[0004] A permanent rasta hairstyle is a hair fashion comprising tightly braided long braids usually comprising thin and extremely strongly interlocked hair strands. These types of hairstyles are also called dreadlocks. Both names are used synonymously in the following description. Ethnic hair (e.g. African or Afro-American hair, so-called kinky hair) is ideal for setting up dreadlocks or rasta hairstyles because of its naturally curliness and its nature. However rasta hairstyles can be set up with other, among others, smooth, hair, such as middle European or Asiatic hair, with suitable techniques. It is necessary however to produce a hair structure that tends to facilitate strongly interlocking the hair strands prior to forming the locks. This usually occurs by a combination of chemical and mechanical treatments of the hair. First it is necessary that the hair is made dull. Hair flake or scale should not be present on the hair shaft, but should be removed as much as possible. The chemical treatment can occur with a hair reducing agent (e.g. thio compounds, such as thioglycolic acid), such as is used in a permanent wave treatment, but with the difference that the effective concentration and/or action is greatly increased. During this latter treatment the cuticle layer is probably at least partially or entirely removed to increase the required tendency of the hair strands to interlock. Another chemical treatment is an alkaline treatment with strong alkali compositions, e.g. corn soap or an alkaline shampoo without care additives. Furthermore an intense mechanical treatment of the hair is required to remove the flake or scale. This can occur by an intense “toupier” of the hair as strong as possible for several hours with a very fine comb, e.g. with a lice comb or similar comb, usually with stable metal teeth. “Toupier” of the hair is also called “back combing”. These terms are used synonymously in the following.

[0005] During back combing there is an intense irreversible interlocking of the hair and the hair is irreparably damaged. Another problem besides hair damage is that the rasta hair style is permanent when set up with the conventional hair techniques and is not removable. The interlocking of the hair is irreversible, i.e. it cannot be reversed without more. Those who set up this hairstyle once only remove it by cutting off the hair with a scissors. Some fashion-conscious users would like to have a rasta hairstyle only temporarily or only for a certain occasion, e.g. for a party on the weekend, and would like to switch back to their original hairstyle the next day without damaging their hair. Thus there is a strong demand for a removable temporary rasta hairstyle that does not entail damaging hair treatment steps.

[0006] An additional problem with the conventionally set up rasta hairstyle is hygienic. There is thus a need for cleaning strongly interlocked hair strands, which is currently difficult or not possible. There is thus a danger that the interlocked hair strands can come apart from within, can be damaged and even break off or fall out. Thus for the user, who wants to have a rasta hairstyle for a long time, a method is thus desirable, which permits the opening or separation of the strands after a certain time. Thus the desired rasta hairstyle can be set up anew after an intense hair cleaning and/or hair care treatment.

SUMMARY OF THE INVENTION

[0007] It is an object of the present invention to provide a method of setting up a temporary rasta hairstyle, which does not suffer from the above-described disadvantages and which can be removed later without damaging the hair.

[0008] It is a further object of the present invention to provide compositions for effectively performing the method of setting up a temporary rasta hairstyle according to the invention.

[0009] It is another object of the claimed invention to provide a multi-part kit for the method of setting up a temporary rasta hairstyle according to the invention.

[0010] It has now been found that these objects can be surprisingly attained by a method according to the invention of setting up a temporary rasta hairstyle and later removing it.

[0011] According to the invention this method includes the following steps:

[0012] a) applying one or more roughening substances to the hair that increases the roughness of the hair surface;

[0013] b) preferably but optionally applying one or more adhesion-increasing substances to the hair to increase adherence of hairs to each other; and

[0014] c) setting up temporary rasta strands by intertwining the hair strand-wise, without essentially, i.e. irreversibly, interlocking the hairs.

[0015] The intertwining of the hair strands can occur e.g. either by gently back combing or by one or more of dividing, drawing apart and twisting the divided hair strands, or by a combination of twisting the strands around their long axis and gently back combing the twisted strands. The cleaning of the temporary rasta hair style can occur using a concave sponge, without destroying the hair style. In order to remove the temporary rasta hairstyle a composition increasing the wet combability of the hair is applied to the hair. The rasta strands are opened and/or unwound, preferably mechanically using an ordinary comb or brush.

[0016] It was surprisingly found that it is possible to produce an authentic or at least nearly authentic rasta-look or rasta appearance, like a “true” permanent rasta, without damaging the hair and without the up to now strongly irreversibly interlocked hairs considered as a prerequisite. Furthermore it was surprising that the removal of the rasta hairstyle is possible simply without problems. The hair makes an even better cared for and healthier impression than prior to treatment after removal of the temporary rasta hairstyle, especially regarding the feel, luster and combability. This is immediately astonishing, since up to now a rasta hair style is almost synonymous with strongly damaged and uncared for hair. Now with the methods according to the invention the opposite has been achieved. The care action is partially what one would have expected from the action of the remover composition C that is described in detail hereinbelow. This means that it is based on a synergistic care action of the remover composition C in combination with the pre-treatment composition A and/or B described in more detail below.

[0017] The subject matter of the invention is thus a method of setting up a rasta hairstyle, in which at least one roughening substance for roughening the hair surface is applied to the hair and subsequently a temporary rasta hairstyle is set up. The term “temporary rasta hairstyle” means a hairstyle with the appearance of a rasta look, which is again removable in contrast to a permanent rasta hairstyle. In contrast to the permanent rasta hairstyle the hair is not essentially or substantially interlocked, but only intertwined, i.e. the hairs that are twisted together can be mechanically separated from each other again. The roughening substance that increases the roughness of the hair surface is a substance, which adheres to the hair surface and causes clean hair to feel rough or dull in contrast to hair that has not been treated. This substance can be applied to the hair by means of composition A, which is described in more detail hereinbelow.

[0018] The stability of the temporary rasta hairstyle is clearly increased when an adhesion-increasing substance that increases the adherence of the hairs with each other is applied to hair and/or to the hair tips that has or have been pre-treated with the roughening substance increasing the surface roughness. The application of the adhesion-increasing substance increasing the adhesion of the hairs with each other can occur by means of the composition B that is described in more detail hereinbelow. The adhesion-increasing substance can be applied either prior to or after setting up the rasta hairstyle as necessary.

[0019] Setting Up of the Temporary Rasta Hairstyle

[0020] To set up the temporary rasta hair style hairs that are predetermined according to the invention are arranged or put in one or more temporary dreadlocks. This can occurs by several methods. One of the three following methods is recommended for doing this. The recommended methods are to be understood as exemplary embodiments. In all of these techniques the setting up of the dreadlocks begins on the neck. Moreover one section (for example of about three cm thick) is divided from side to side transversely to the head. The base surface of the individual dreadlocks (individual strands) depends on the desired thickeness/density, amounting usually to 6 to 9 cm² and can be square, rectangular, trapezoidal or triangular. One works in the direction of the forehead in these methods or techniques. The dreadlocks are laid over each other in the manner of shingles. In order to improve the planed hairstyle, the dreadlocks are preferably held directly in the desired direction during setting up of the hairstyle.

[0021] An Especially Preferred Method

[0022] The separated individual strand is uniformly gently back-combed (intertwined, not interlocked) with a back comb from the hair roots to the hair tips. During the back combing the individual strand is twisted over its long axis, whereby a special round and “true” appearing dreadlock is produced.

[0023] An Additional Preferred Method

[0024] The separated or divided individual strand is strongly twisted with the fingers over its long axis. After 2 to 3 twists the hair strand is arbitrarily divided at the tips. Both hair strands arising by the division are now spread from each other, whereby the two to three prior twists move toward the hair roots and intertwine (similar to back bombing). The twist, division and spreading of the hair strand is performed until the entire length of the individual strand is intertwined.

[0025] Additional Possible Method

[0026] The separated or divided individual strand is strongly twisted with the fingers over its long axis, until the entire strand is effectively “knurled”. The hair tips of the hair strand are held fixed and the spreading on the long axis is somewhat reduced. Now the already twisted strand is gently back combed with a suitable back comb, without interlocking the hairs. The back combing occurs over the entire axial length of the individual strand. After that the twisted and back combed strand is rolled between the thumb and index finger once more in order to augment the intertwining effect.

[0027] Composition A

[0028] The application of the roughening substance increasing the roughness of the hair surface can occur by means of a first composition A. Suitable substances are e.g. those substances, which are solid at room temperature (25° C.) and are present in the form of particles. Silica, silicates, aluminates, clays, micas, salts, especially inorganic metal salts, metal oxides, e.g. titanium dioxide, minerals and polymers are somewhat suitable. Polymers, which impart a rough dull feel to the hair, are suitable. The suitability of a polymer is established by half-side tests of polymerically treated hair in contrast to untreated hair.

[0029] Suitable roughening polymers are, for example, copolymers of alkylacrylamides, especially C₁-C₈-alkyl groups, and at least one monomer selected from the group consisting of acrylic acids, methacrylic acids and their simple esters, especially the C₁- C₄-alkyl esters (INCI: acrylates/octylacrylamide copolymer, acrylates/t-butylacrylamide copolymer, e.g. Amphomer® HC and/or Ultradhold® 8); copolymers of vinyl methyl ether and alkyl hemiesters of maleic acid, especially C₁-C₅-alkyl hemiesters (INCI: butyl ester of PVM/MA copolymer, e.g. Gantrez® ES 425; copolymers of vinyl acetate and crotonic acid (INCI: VA/crotonates copolymer, e.g. Luviset® CA 66).

[0030] The roughening substance can be present in the form of solid particles in the composition A and preferably the solid particles are dispersed in the composition to form a stabile dispersion. Alternatively they can be present in dissolved form in a suitable cosmetically acceptable solvent. They are then separated from the solution after applying the solution to the hair and evaporating the solvent. A stabile dispersion can be attained, when the composition A is provided with a flow limit, which is sufficiently large, in order to prevent the settling of the solid particles. A sufficient flow limit can be adjusted to a suitable value by using a suitable gel former.

[0031] Silica (silica gel, silicon dioxide) and metal salts, especially inorganic metal salts, are especially preferred as the roughening substance applied to the hair. Silica is most preferred. The metal salts include, e.g., alkali or alkaline earth metal halides, such as sodium chloride and potassium chloride; alkali or alkaline earth sulfates, such as sodium sulfate or magnesium sulfate. In the event that a soluble metal salt is used composition A is preferably an aqueous solution of this salt and is preferably in combination with a spraying device, e.g. a mechanically operated spray pump. In case insoluble particles are used, which are not soluble in water, alcohol and/or an alcohol/water mixture, such as silicon dioxide or a metal oxide, composition A is preferably a gel having a flow limit or yield point and contains at least one gel former that establishes the flow limit. Alternatively composition A is a foamable composition containing at least one foam-forming surfactant and/or foam-forming polymer. The foaming can occur by an aerosol propellant or by means of a mechanically operated apparatus for making foam.

[0032] In the case of the embodiments of composition A that are gel, thickening polymers are included, which impart a plastic or pseudo-plastic behavior to the compositions. The rheological flow properties of the gel according to the invention are characterized by the existence of a flow limit. The flow limit preferably amounts to at least 3 Pascal, measured with a Haake Rotation Viscometer RV 12, measurement system PKV-0.5 at 30° C. and at a linearly increasing shear rate of 0 to 100 s⁻¹. After exceeding the flow limit the gel preferably has a viscosity of 1,000 to 100,000 mPa.s, especially from 5,000 to 50,000 mPa·s at 25° C., measured with a Haake Rotation Viscometer Type VT 501 at a shear rate of 12.9 per second. The flow point or flow limit is selected according to weight and surface area of the particles so that it is at least as large as the pressure exerted by the particles. The settling of the particles is thereby prevented. The thickeners are preferably contained in an amount of from 0.05 to 10, especially preferably from 0.1 to 4, percent by weight, in composition A. The optimum concentration is dependent on the type of thickener and the weight of the particles. Suitable thickeners are cross-linked or not cross-linked polyacrylic acids or polymethacrylic acids. These thickeners, which can be contained in the compositions according to the invention, include homopolymers of acrylic acid with a molecular weight of 2,000,00 to 6,000,000 g/mol, which are marketed e.g. by Goodrich, USA under the trademark Carbopol®. Additional thickeners are e.g. the acrylic acid polymers, acrylic acid/acrylamide copolymers or Sclerotium Gum, marketed under the trademark Modarez® V 600 PX of Protex, France or under the trademark Carbopol® ETD 2001 by Goodrich, USA. Copolymers of acrylic acid or methacrylic acid, such as those marketed under the trademark Carbopol® 1342 or Pemulen® TR1 of Goodrich, USA, are suitable. Guar gum, xanthan gum, bentonite and hectorite are additional suitable thickeners.

[0033] In an advantageous embodiment of the composition thickeners are included in the composition besides those that impart a sufficient flow limit or flow point in the viscosity range typical for gels in addition to those thickeners that impart a sufficient flow limit or flow point to the composition. These latter thickeners include especially cellulose and cellulose derivatives, such as carboxymethyl cellulose, cellulose ether and hydroxyalkyl cellulose compounds. The thickeners contain acid groups, which are at least partially neutralized with cosmetically compatible bases. Suitable organic or inorganic bases that are appropriate for cosmetic applications can be used as the neutralizing agents. For example, the bases can include amino alcohols, such as aminomethylpropanol (AMP), triethanolamine or monoethanolamine and ammonia, NaOH and others.

[0034] Composition A also can be in the form of an aerosol or non-aerosol sprayable or foamable product. The aerosol products include a pressure-tight aerosol container with a spray or foam head, which contains the foamable or sprayable composition. The pressure-tight aerosol container of the aerosol spray product according to the invention can be made from any material known for aerosol spray or foam products. Metals, such as aluminum or tin, are especially suitable materials. Preferably the aerosol propellants are employed in an amount of from 1 to 20, especially preferably from 2 to 10, percent by weight. For example, lower alkanes, such as n-butane, i-butane, propane, butane, or also their mixtures and dimethyl ether or fluorohydrocarbons, such as F 152a (1,1-difluoroethane) or F 134 (tetrafluoroethane) are suitable as the aerosol propellants. In addition, propellants present in compressed gaseous form, such as N₂, N₂O and CO₂, and their mixtures are suitable as the propellants.

[0035] Preferably the composition comprises an aqueous or an aqueous-alcoholic medium with preferably at least 10 percent by weight water. The solvent system is preferably present in the composition in an amount of 50 to 98, especially preferably from 75 to 95, percent by weight. The alcohols included in the solvent system especially include lower alcohols having one to four carbon atoms that are suitable for cosmetic purposes, such as ethanol and isopropanol. Organic solvents or mixtures of solvents with a boiling point under 400° C. are suitable as co-solvents in amounts of from 0.1 to 15, especially from 1 to 10, percent by weight. Branched or unbranched hydrocarbons, such as pentane, hexane, isopentane and cyclic hydrocarbons, such as cyclopentanes and cyclohexane, are suitable as additional co-solvents. Glycerol, ethylene glycol and propylene glycol are additional especially suitable water-soluble solvents.

[0036] In the case of non-aerosol sprays and non-aerosol foams, the compositions are present in combination with a mechanically operated apparatus for spraying or forming.

[0037] The foamable products usually contain at least one foam-producing substance, e.g. a foam-forming surfactant and/or a foam-forming polymer. The surfactant can have nonionic, anionic or amphoteric character. Nonionic foam-forming surfactants are preferred. The surfactants can be used individually or in a mixture. The amount of the surfactants can be varied and is selected so that a sufficient amount of foam is formed for working into the hair, when the composition is delivered from the aerosol container or the product dispenser. The surfactant amount is preferably typically from 0.01 to 5, especially preferably from 0.1 to 2, percent by weight. Suitable nonionic surfactants are, for example, the C₈- to C₁₈-fatty alcohols, which can be ethoxylated with from 8 to 45 mol ethylene oxide, e.g. lauryl alcohol, tetradecyl alcohol, cetyl alcohol, oleyl alcohol or stearyl alcohol, ethoxylated with up to 40 mol ethylene oxide per mol fatty acid, alone or in a mixture; hydrogenated castor oil ethoxylated with 8 to 45 mol ethylene oxide; C₈- to C₁₈-fatty acid alkanolamides; fatty alcohols of ethoxylated lanolin orethoxylated lanolin; polyglyceryl ethers of saturated or unsaturated fatty alcohols and alkyl phenols with 8 to 30 carbon atoms in alkyl groups and with 1 to 10 glyceryl units per molecule; polyethylene/polypropylene block copolymers and ethoxylated sorbitan fatty acid ester. Derivatives of natural surfactants, e.g. alkylpolyglycosides, are especially preferred as the nonionic surfactants. For example, alkyl sulfates, alkyl ether sulfates, alkyl sulfonates, alkoyl sarcosinates, akly isethionate or dialkylsulfosuccinates, which contain from 8 to 18 carbon atoms, are suitable anionic surfactants. Betaines are especially suitable as amphoteric surfactants. For example, the betaines include C₈- to C₁₈-alkyl betaines, such as cocodimethylcarboxymethylbetaine, lauryldimethylcarboxy-methylbetaine, lauryldimethyl-alpha-carboxyethylbetaine, cetyldimethylcarboxy-methylbetaine, oleyldimethyl-gamma-carboxypropylbetaine and lauryl-bis-(2-hydroxypropyl)-alpha-carboxyethylbetaine; C₈- to C₁₈-sulfobetaines, such as cocodimethylsulfopropylbetaine, stearyldimethylsulfopropylbetaine, lauryldimethylsulfoethylbetaine, lauryl-bis-(2-hydoxyethyl)sulfopropylbetaine; the carboxyl derivatives of imidazoles, the C₈- to C₁₈-alkyldimethyl ammonium acetates, the C₈- to C₁₈-alkyldimethyl carboxymethyl ammonium salts and the C₈- to C₁₈-fatty acid alkylamidobetaines, such as coconut fatty acid amidopropylbetaine, and N-coconut fatty acid amidoethyl-N-[2-(carboxy-methoxy)ethyl]glycerol (CTFA: cocoamphocarboxyglycinate).

[0038] Composition B

[0039] The application of the adhesion-increasing substance causing the hairs to adhere to each other can occur by means of a second composition B. Suitable substances are, e.g., waxes, waxy materials and/or adhesive polymers. Waxes and waxy materials are especially those substances with the properties according to the definition of waxes in Ullmanns' Encyclopedia of Industrial Chemistry, 4^(th) Edition, Volume 24, page 3. According to this Encyclopedia the waxes are kneadable at 20° C., solid to brittle and hard, fine to gross crystalline, at least translucent to opaque, however not glassy, melting over 40° C. without decomposition, comparatively low viscosity a little over its melting point, strongly temperature dependent in its consistency and solubility and polishable under a gentle pressure. In the following the terms “wax substance” and “waxy or wax-like substance” are synonymous in the following. Adhesive polymers, which are suitable, include those polymers, which impart an adhesive feel to the hair, as established by half-side tests of polymerically treated hair in comparison to untreated hair.

[0040] Suitable hydrophobic waxes include animal, plant, mineral and synthetic waxes, microcrystalline waxes, solid paraffins, petrolatum, Vaseline®, ozokerite, montan wax, Fischer-Tropsch wax, polyolefin waxes, for example polybutene, beeswax, wool wax and its derivatives, e.g. wool wax alcohols, candelilla wax, carnauba wax, Japan wax, hardened fats, fatty acid esters and fatty acid glycerides with a solidification point of over 40° C., polyethylene waxes and silicone waxes. The waxes have a solidification point of over 40° C., preferably over 55° C. The needle penetration number (0.1 mm, 100 g, 5 s, 25° C., according to DIN 51 579) is preferably in a range of from 2 to 70, especially from 3 to 40, especially preferably less than 20. Carnauba wax, ceresin wax and their mixtures are especially preferred. The waxes and waxy materials in composition B are preferably contained in an amount of from 4 to 50, especially preferably from 8 to 30, and particularly preferably from 10 to 25, percent by weight.

[0041] In an especially preferred embodiment composition B is an aqueous emulsion of a hydrophobic wax and contains at least one emulsifier and water in addition to the wax. The term “emulsion” includes wax dispersions in water, but also suspensions of solid wax particles in water. The emulsifiers are, preferably, contained in an amount of 0.5 to 50, especially from 3 to 40, and particularly from 20 to 35, percent by weight.

[0042] Preferably the emulsifiers are nonionic surfactants. The following emulsifiers are especially suitable:

[0043] addition products of 2 to 30 mol ethylene oxide and/or 1 to 5 mol propylene oxide to C₈- to C₂₂-fatty alcohols, to C₁₂- to C₂₂-fatty acids or to alkanol phenols with C8- to C₁₅-alkyl groups;

[0044] C₁₂- to C₂₂-fatty acid monoesters or diesters of addition products of from 1 to 30 mol ethylene oxide to glycerol;

[0045] addition products of 5 to 60 mol ethylene oxide to castor oil or to hardened (hydrogenated) castor oil; and

[0046] mon-, di- and triesters of phosphoric acid with addition products of 2 to 30 mol ethylene oxide to C₈- to C₂₂-fatty alcohols.

[0047] In an especially preferred embodiment the total amount of the emulsifiers present is larger than the total amount of the waxes. That means that the weight ratio of the emulsifier to wax is larger than 1:1, preferably up to 5:1, especially preferably from 1.5:1 to 3:1. These embodiments are characterized by a combination of individual active ingredients. Directly after the application to the hair the adhesion force of the hairs is very high, which very much simplifies the setting up of a rasta hairstyle. After drying the adherence is greatly reduced, which leads to an improved pleasant feel. A reduced, not unpleasant, residual adhesion remains and causes the finished rasta strands to adhere loosely to each other, which provides additional fresh hair styling possibilities. The preferably advantageous automatically decreasing adhesion force is especially strongly expressed in combination with silica as the roughening substance that increases the roughness of the hair. An additional especially advantageous effect is the sufficiently good residue-less removal of the hydrophobic wax, especially using the composition C described further below for removing the rasta hairstyle. Composition B is present ideally in liquid, i.e. liquid or viscous form. It is preferably dispensed in liquid form by means of a pumping device, sprayed as a spray by means of a spraying device or as foam with an apparatus for producing foam. For additional ingredients for the aerosol and non-aerosol embodiments reference is made to the similar ingredients described above as suitable for composition A.

[0048] As waxes however hydrophilic waxes can be used, especially high molecular weight polyethylene glycols (PEG). The polyethylene glycols are preferably waxy solids at room temperature (20 to 25° C.) or at least soft waxy-like compositions with a solidification temperature at about 30° C., preferably at about 40° C. The molecular weight amounts to preferably from 850 to about 5000 g/mol, especially preferably from 1200 to 3500 g/mol. Polyethylene glycols have the general formula H(OCH₂CH₂)_(n)OH. Suitable high molecular weight polyethylene glycols are, e.g., those with n=19 to 113, preferably with n=30 to 79. Suitable polyethylene glycols have the INCI-name PEG-20 (n=20), PEG-32 (n=32), PEG-60 (n=60), PEG-75 (n=75), PEG-90 (n=90) and PEG-100 (n=100). Commercial products usually have a molecular weight distribution. Suitable commercial products are, e.g., polyglycol 1000, polyglycol 1350, polyglycol 1500, polyglycol 3000 or polyglycol 4000 of Clariant. The numerical values designate approximately the average molecular weight.

[0049] Rasta-Cleaning

[0050] To care for the temporary rasta hairstyle as careful as possible a cleaning without application of greatly stressing the rasta strands is recommended. Careful cleaning comprises moistening the hair and then applying a hair cleaning composition, which contains at least wash-active surfactant, to the hair or a sponge. Then the composition is cautiously distributed on the hair, e.g. by dabbing with the sponge. Subsequently the cleaning composition is removed from the hair, which occurs by rinsing with water or by dabbing with the sponge after rinsing it many times in the meantime. The sponge preferably has a concave shape. The concave shape approximately corresponds to the shape of the head. The application, distribution and/or removal of the cleaning composition on the hair occur with the concave inner side of the sponge.

[0051] Rasta-Removal The removal of the temporary rasta-hairstyle set up according to the invention can occur by moistening the hair, applying a remover composition C to the hair and distributing it on the hair. The rasta strands are then opened or unwound. Finally the composition C can be rinsed from the hair.

[0052] Composition C

[0053] The composition C contains at least one substance that enhances the wet or moist combability. This combability enhancing substance is preferably contained in the composition C in an amount of from 0.01 to 10, especially preferably from 0.05 to 5, percent by weight. For example, cationic polymers, cationic surfactants, amine oxides, cationic silicone compounds, oil ingredients, fatty alcohol and glycerol fatty acid monoesters, are suitable. Suitable cationic surfactants include those, which contain a quaternary ammonium group and at least one organic residue with at least six carbon atoms. Suitable carionic surfactants can be of the general formula:

N⁽⁺⁾R¹R²R³R⁴X⁽⁻⁾

[0054] wherein R¹ to R⁴ each represent, independently of each other, an aliphatic group, an aromatic group, an alkyoxy group, a polyoxyalkylene group, an alkylamido group, a hydroxyalkyl group, an aryl group or alkylaryl group, each of the foregoing groups having from 1 to 22 carbon atoms, wherein at least one of the groups has at least six carbon atoms and X- represents an anion. The anion can be a halogen anion, acetate, phosphate, nitrate or alkyl sulfate, preferably a chloride anion. The aliphatic group can contain cross-linking or other groups, such as amino groups, in addition to the carbon and hydrogen atoms. The groups can be linear, branched or cyclic. For example, the following are suitable cationic surfactants: the chlorides or bromides of alkyldimethylbenzyl ammonium salts, of alkyltrimethyl ammonium salts, for example cetyltrimetyl ammonium chloride or bromide, tetradecyltrimetyl ammonium chloride or bromide, alkyldimethylhydroxyethyl ammonium chloride or bromide, the dialkyldimethyl ammonium chloride or bromide, alkylpyridinium salts, especially lauryl or cetylpyridinium chloride, alkylamidoethyltrimethyl ammonium ether sulfate and compounds with cationic character, such as amine oxides, for example, alkylmethylamine oxide or alkylaminoethyldimethylamine oxide with at least six carbons in the alkyl groups. Cetyltrimethyl ammonium chloride is particularly preferred as the cationic surfactant.

[0055] Cationic polymers in the sense or the present invention are those polymers, which contain at least one cationic or cationizable group that becomes a cationic group when protonated. Cationic groups, for example, include quaternary amine groups. Cationizable groups, for example, include primary, secondary or tertiary amine groups. The cationic polymers can be homopolymers or copolymers, in which the cationic or cationizable groups are either in the polymer chain or preferably present as substituents on one or more of the monomers.

[0056] Suitable monomers of the cationic polymer, which have cationizable groups, are unsaturated radically polymerizable compounds, which have at least one neutralized or not neutralized basic group. The basic groups can include especially primary, secondary or tertiary amine groups. The amine nitrogen can also be part of a ring. For example, the monomers of this type include monoalkylaminoalkylacrylates or -methacrylates and dialkylaminoalkylacrylates or -methacrylates. The Alkyl groups of these monomers are preferably lower alkyl groups, such as C₁- to C₇-alkyl groups, especially preferably C₁- to C₄-alkyl groups.

[0057] Suitable monomers, which have quaternary amine groups, are unsaturated radically polymerizable compounds, which have at least one quaternary amine group. These monomers preferably include ammonium substituted vinyl monomers or quaternarized derivatives of carboxy vinyl monomers, such as quaternarized acrylamides or methacrylamides. For example, acrylamidoalkyltrialkyl ammonium halides or methacrylamido-alkyltrialkyl ammonium halides, trialkylmethacryloxyalkyl ammonium halides, trialkylacryloxyalkyl ammonium halides, dialkyldiallyl ammonium halides or quaternary vinyl ammonium monomers with groups containing cyclic, cationic nitrogen, such as pyridinium, imidazolium or quaternary pyrrolidone, e.g. alkylvinylimidazolium, alkylvinylpyridinium, or alkylvinylpyrrolidone salts, are suitable. The alkyl groups of these preferred monomers preferably include lower alkyl groups, such as C1- to C₇-alkyl groups, especially preferably C₁- to C₃-alkyl groups. Acrylamidopropyltrimethyl ammonium chloride and methacrylamidopropyltrimethyl ammonium chloride are particularly preferred.

[0058] The cationic polymer can be polymerized, as needed, with neutral comonomers, which contain neither cationic nor cationizable groups.

[0109] This composition is provided in a container with a pump spray apparatus.

[0110] Washing of the Rasta Hairstyle

[0111] The hairstyle is sufficiently moistened with a shower or gentle water jet under the shower. A mild shampoo is applied to the concave inner side of a concave moistened wash sponge. By dabbing the hair-do (no circular motions) foam is produced from the shampoo. However it is rinsed away gently. After the washing the dreadlocks are again twisted or rotated using composition B.

[0112] Removal of the Rasta Hairstyle

[0113] After washing a cationic hair care composition of the following composition C is worked into the moist hair. 6.0 g Cetearyl alcohol 1.35 g Vaseline ® 1.2 g Paraffinum Perliquidum 1.0 g Cetyltrimethyl ammonium chloride 0.3 g Lanolin alcohol 0.15 g Lanolin 0.5 g Silicone oil 0.5 g Citric acid to 100 g water
